Combine Essentials: Publishers, Subscribers, and Subjects
Course Description
Combine is Apple’s powerful framework for handling asynchronous data, event streams, and state updates in a declarative way. This course takes you step by step from the basics of reactive programming to building complete, data-driven SwiftUI apps using Combine for iOS development.
You’ll start by learning what Publishers, Subscribers, and Operators are—and how they connect data flow through your app. From there, you’ll explore two core types of Subjects, PassthroughSubject and CurrentValueSubject, to understand when to broadcast new events and when to manage application state.
Through clear explanations and real-world coding projects, you’ll learn how to:
Use Combine to handle network requests, decode JSON, and update SwiftUI views seamlessly.
Simplify async code by replacing completion handlers and async/await with data pipelines.
Understand the difference between stateful and stateless data streams.
Integrate Combine effectively within the MVVM architecture for scalable applications.
Manage subscriptions, memory, and data flow in reactive apps efficiently.
By the end of this course, you’ll have the knowledge and confidence to use Combine effectively in your Swift projects—making your code cleaner, more scalable, and ready for modern iOS development with reactive programming principles.
Perfect for: Intermediate Swift developers, SwiftUI learners, or anyone who wants to master Combine’s core concepts and apply them in real-world iOS apps.
